A Trip Inside

For those curious to see what goes into a Rabid Elephant instrument...

components

CONTROLS

We use low-noise sealed conductive plastic element potentiometers rated for 1 million cycles. This is 100x longer than the carbon pots found in nearly all other electronics. Our pots also feature solid metal bushings and shafts for ruggedness. The feel is perfect. Not too fast, not too slow and silky smooth. Faders are also conductive plastic and rated for 100k cycle life, 10x longer life than most others.

Rabid Elephant knobs are custom made for us from impact resistant polycarbonate. We have tested hundreds of knobs and these, to our fingers, are perfection - balancing comfort, speed, and precision. The chamfered roof provides visual and tactile readability at all pot rotations. Skirted knobs allow the finger to find 'home' without having to drag against the fascia causing uncontrollable/uneven friction.

We use premium optical encoders instead of inexpensive mechanical encoders which wear out and begin skipping steps in only a few years of moderate use.

Tact pushbuttons are sealed and rated for 1 million cycles or better. We use Salecom silver contact toggle switches featuring 100k cycle life.

PASSIVES

We use high-spec, low noise, low drift, low tolerance, low tempco resistors. All resistors are at least 1% tolerance and 0.05% in 'generic' critical areas, typ. 25ppm. For ultra-precision reference circuitry, we use 0.05% laser trimmed matched resistor packs. All signal path resistors are thin film and spec'd for very low distortion and excellent linearity. We also spend similar care in selection of the right capacitors.

OP AMPS

We use some of the highest performance op amps available to date for ultra-high precision and negligible temperature drift. This allows for simpler, higher precision signal paths. Noise and THD are negligible for these devices. They are also rail-to-rail which means you gain nearly 4V total headroom over other commonly used devices.

CONNECTORS

Power connectors are keyed, latching, long-life, low resistance gold plated Samtec Rugged Mini-Mate. We use 24 & 20AWG wire which provides very low voltage drop compared to ribbon cables which use 26-28AWG wire. Our power cables will last over 3x longer than typical Euro power cables all while providing lower ground losses and less noise - which becomes more and more apparent as a modular system grows in size.

PANELS

We have recently changed our panel technology to a fiberglass-based panel. This has nothing to do with cost (they actually cost more the way we have them made!) We did this to provide a much better aesthetic (gold is real gold, not a yellowish printing) and the silk screen pops and is much easier to read in low-light conditions. We can also do more clever things with lighting and surface switches.

We also put brushed ferritic stainless backing plates on all of our modules. This offers EM shielding, a bit of thermal isolation, and keeps the electronics of the module protected. We mill proper Eurocard compatible slotted holes for use of captive screw fasteners (contact us for details) so no more dropping or losing screws.

ERGONOMICS and PLAYABILITY

Tactile feedback and ergonomics are essential for an instrument to become a natural extension of the body and mind. Our instruments feature comfortable, easy, and inspiring user interfaces.

Our user-interface layouts and aesthetic come from Hannes Pasqualini. You can learn more about his excellent work here.

PRECISION

Some of our instruments feature repeatable precisions in the sub-100uV range. This unique level of repeatability allows you to keep magical patches just the way they should be.

POWER and GROUNDING

Our modules feature separate analogue, digital, and chassis grounds in order to carefully control noise from entering precision CV or audio signals..

A rugged properly polarised, latch-locking power connector is used on all of our modules. It features lower contact resistance and large wire for lower drop across your modular system (which results in lower noise floor).

We add active, high-speed, low-loss reverse voltage protection for maximum headroom and over-voltage protection for digital sections. All rails feature over-current protection. For any module with digital devices on-board, we provide user-selectable voltage source for those without a dedicated 5V rail.

INDICATORS

LED indicators placed off analogue rails is fully balanced and constant current for zero switching noise on the analogue grounds, which would otherwise result in audible 'clicks' as an LED transitions.

RELIABILITY

We expect our instruments to be lifetime instruments. You won't worry about scratchy controls, skipping encoders, uneven/sloppy 'feel', snapping off a knob, or any of the other issues you've likely encountered with inferior electronics. We feel our design and build quality and overall unwillingness to make compromises is something largely missing in products produced today.

BURN-IN

All of our products are fully burned in for 24 continuous hours before final testing. This increases the chance any semiconductor, joint, or other failure modes are discovered before the instrument is shipped.

SOFTWARE

All software is professionally designed and tested which means fewer bugs and quick, responsive operation. Our menus are almost always 1:1 and for less frequently used settings or modes, we limit menu depth to 1 additional layer - but are still sure to clearly mark them on the panel.
